I read the Direct Energy contract pretty carefully. I believe Thinkxingu did as well and I hope he will chime in. I couldn't see any downside. I was cautious like you, but I'm very glad I switched to Direct Energy. I'm kicking myself for not doing this long ago. They had an even cheaper price before the current $.1699.
The terms of service are here:

PLUS: you can earn $50 for each person you refer who signs up with Direct Energy. The friend also gets $50. Would you like me to refer you?
